Deleted-

1. (Motivate) If a perpendicular is drawn from the vertex of the right angle of a right

triangle to the hypotenuse, the triangles on each side of the perpendicular are similar

to the whole triangle and to each other.

2. (Prove) The ratio of the areas of two similar triangles is equal to the ratio of the

squares of their corresponding sides.

3. (Prove) In a right triangle, the square on the hypotenuse is equal to the sum of the

squares on the other two sides.(Pythagoras Theorem)

4. (Prove) In a triangle, if the square on one side is equal to the sum of the squares on the other two sides, the angle opposite to the first side is a right angle.(Converse of Pythagoras Theorem)
